ATTACHMENT FOR MUSICAL INSTRUMENTS.

Specification of Letters Patent.

Patented Jan. 30, 1906.

To will whom it may concern.-

Be it known that I, JOHN O. HOUSER, a

citizen of the United States of America, re-

siding at Pittsburg, in the county of Allegheny and State ofPennsylvania, have invented certain new and useful Improvements vin-Attachments for Musical Instruments, of which the following is aspecification, reference being had therein to the accompanying drawings.

This invention relates to certain new and useful improvements inattachments for musical instruments, and more particularly to anattachment adapted to be used in connecproduce sounds that are hardlyaudible, the

tones of which are indistinct and cannot be appreciated. Myattachment'aims to eliminate the harsh notes or sounds produced by themusicalfinstrument and to improve the indistinct and inaudible sounds ornotes of an instrument. an attachment which can be used in connectionwith different types of musical instruments,such as horns, and theconstruction of the attachment enables me to manufacture the same at acomparatively small cost, at

' the same time maintaining a construction of durable nature.

With the above and other objectsin view the invention finally consistsin the novel construction, combination, and arrangement of parts, whichwill be hereinafter more fully described and then specifically pointedout in the claims, and, referring to the drawings accompanying thisapplication, like numerals of reference designate corresponding partsthroughout the several views, in which Figure 1 is a side elevation of agraphephone equipped with my improved attachment. Fig. 2 is a sideelevation of the attachment. Fig. 8 is an end view of the same.

Fig. 4 isa vertical sectional view of the attachment. Fig. 5 is an endview of a portion of my improved attachment, illustrating a To this endI have devised transversely of the pipe 3.

and Fig. 7 is an end view of a portion of the same.

In the accompanying drawings I have illus trated the attachment asapplied to a graphophone simply to show the manner in which it is usedwith such an instrument.

The attachment proper, which is illustrated in Figs. 2 t0 5, inclusive,consists of two members 1 and 2, each of which is provided with anoutwardly-extending tube or pipe 3. These members 1 and 2 aresubstantially in the form of segments of spheres, preferably ofdifferent peripheral diameters or a purpose as will presently ap ear.The periphery of the member 1 is prefiirably of a greater diameter thanthe periphery of the member 2, whereby when these members are placed inengagement with one another the peri hery 4 of the member 1 can be bentinwar ly or reamed to engage the member 2 and form a casing for adiaphragm 5. This diaphragm is preferably made of thin sheet steel,rubber, or the like resilient metal ormaterial, and the diaphragm issubstantially the'shape in top plan view of a Maltese cross, theperipheral edges 6 6 of the diaphragm being retained between theperipheries of the members 1 and 2.

One of the tubes or pipes 3 is provided with a regulator 7 substantiallyof a dam er form, this regulator consisting of a circu ar plate 8,mounted upon a rod 9, journaled The ends of the pipes 3 3 are slotted,as indicated at 10 10, to

permit of the ends being contracted or expanded, as it may be desired,when securing my improved attachment upon an instrument.

In Figs. 6 and 7 of the drawin s I have I have employed the regulatorsfor improving and controlling the volume of sound passing through myimproved attachment, it being possible by the adjustment of theregumounted struments and. when 'QIOPQETi" reguiesed is :0 capable ofregulating the sound feeiiities (if any insbrumeni, is which it sppiiei.

What 1 claim, and. desire to seizure by Let tel-s Patent, ie-

1. An etteebmens ier nwsieei insizrumen'bs 15 consisting of two members,e11 outwardlyextending pipe carried by each member, the ends 01 saidpipes bein siested, e re almer mounted in one of pipes, dieehyegminterposed between. said membe H10. means some secure said memberstogether, substentieiiy as deseribeoi. I 2. An attachment fer musicalinstruments consisting of two members substentiaiiy. in the" felm ofsegmei'i'bs 01 spheres, a diaphragm 25 interposed between said. members,a reguie-- tor eerried by one of seid members, and

in. an attachment for musical instru meets, she combination with aninstrument sepebie of producing e sound, of two mem bers, diaphragmmounted. between said members, means to secure said members together,means to regulate the sounds passing
